`To all whom t mwjz/ concer/n Y Be it known that I, ROBERT HUDSON WaeER, a4 citizenof the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certaln new and useful Improvements in Lather-Forming Processes; and -I do 4declare the following to be a full, clear, 4and exactl description of the invention, such as will enable' others skilled in the art to which it appertains to make and use the same.

In barber shops and .similar establish-V ments, it was formerly ,customary to kmix shaving lather in a mug lby means of a brush and to repeatedly use the same brush and mug when shaving different patrons. For reasons of sanitation, this is very objectionable and it is the. object `of' my invention to provide an improved process of forming the lather, which-will dispense with the use of the mug-and brush, yet will produce a lather of a thick creamy consistency: essential to proper shaving.,

The present application forms a division of aprior U. S. application. S. N. 544,059, .filed March 15, 1922, and in the accompanying drawing, I have illustrated an apparatus disclosed by said priorV application, for v carrying out the process covered by the present case, it being understood,'however,

- that numerous other apparatuses can be usedto advantage. v t Figure 1 of the drawing illustrates a verticalsectional view, partly in elevation, of

vthe apparatus. v v Figs. 2 and 3 are sectional views as indicated by lines 2--2 and 3 3 of Fig. 1.

Fig. 4 is -an elevation of a somewhat different Iform of apparatus. In one aspect, Ymy invention may be de'- scribed as consisting in effecting contact of a fluid under pressure, preferably air, with a `soapy' liquid, and by fluid pressure, foro-'- ing the co-mingled liquid and Huid to oozev vthrough screening means, preferably a plurality of screens until a .thick creamy lather suitable for shavingis formed. Preferably after eifecting contact of the soapy liquid arid fluid under pressure, they are converted """iint' minute cells by jointly forcing them through initial screening means. en, these minute cells are converted into a thick creamy. lather, by forcing them through adv ditional screening means, in mostinstances nected to an air tank, a valve 14is used to formed of a plurality of screens.

@have found that excellent results are obtalnable .by first forming soap bubbles and by forcingthese bubbles against screen- 1ng means withno liquidother than their vesicles. Preferably thebubbles are'formed byiaeratmg afsoapy liquid in a closed conl talner and the air pressure in this container eoY is used to force the bubbles against they l screening means Which-converts` them into Q5 the creamy lather. p i

The apparatus shown comprises a container 1 having a water inlet 2, and a supporting platform 3 for as'oaD cake `4 showing soap being preferably used. On its 7 .lowerside', the .platform 3 is formed with a hollow attaching neck v5 and with substantially radial ribs 6, the neck being formedv with air ports l7 between said ribs. The neck 5 `is threaded into' the bottom ofthe container 1 and communicates with anair port 8 in a neck 94 extending downwardly from said container. .In Fig. 1 the neck 9 is coupled by a valve body -10 to a compressed air tank 11, while in Fig. 4 which constitutes the preferred construction, said neck is connected with a tube 12 leading from a hand bulb 13 by which the air is forced into `the soap and water compartment. Itwill be obvious that when using a common hand bulb as shown at 13, no very great superatmospheric pressure can be produced. Y A suitable check valve 14 is shown in the neck 9 and when this neckis con- 90 control the passage of vair into the container 1. At 15, a cap is shown for the container 1', said'cap having a'central recess 16 and an elongated passa-ge 17 around the same, said 95 recess being in. communication with the container 1. One end of the passage 17 communicates with the recess l'through a port 18 'andthe other end of said passage discharges into a spout 19 with which the cap 15 is rovided. Discharge ports 20 are shown 1n the spout 17, but arenot essential.

Between the recess 16 and the interior of the container 1, a screen 21 has been shown, 105 and across the passage 17, additional screens 22 have been illustrated, in spaced relation.

The necessary soapy liquid is formed (when using the apparat-us shown) by placing a. soap cake 4 on the platform 3 and partly filling the container 1 with water. The water compartment is preferably of such a size as to accommodate only a small amount of water. Preferably the amount of water employed at a single filling, is only suicient to create enough lather for one shave, and with this small amount o f water, the device can be tilted Without causing the water to pour (as liquid) out through the lather outlet passage. Warm water is preferably used. Air unde-r low pressure is then brought into contact with the soapy liquid by admitting it through the port 8, and the construction shown will cause the air to Whirl the water around the soap cake to form a soapy liquid of the desired quality. E'eeting contact of the liquid and air by aerating the former, in the foregoing or any adequate manner, will co-mingle the liquid and air and form soap bubbles in the container, and the accumulating air pressure in this container is utilized to discharge the co-mingled air and liquid through the screening means by which it is converted to a thick creamy lather. When the co-mingled air and liquid is forced through the initial screen 21, it is more intimately mixed and converted into minute cells and when these cells are forced along the passage 17 and through the additional screening means 22-22, they are converted into a thick creamy lather which oozes from the spout 19 and may be taken on the hand and thereby applied to the face, or the lather can flow from the spout 19 directly upon the face, without the necessity of using a brush.

I claim:

1. A process of forming a thick creamy shaving lather consisting in effecting contact of an undissolved gas under pressure with a volume of a soapy liquid, the gas and liquid being in such proportions as to form bubbles, and repeatedly screening the comingled liquid and gas under the influence of such a degree of gas pressure as can readily be produced by squeezing a hand bulb, until a thick creamy lather suitable for shaving purposes is obtained.

2. A process of forming a thick creamy shaving lather consisting in aerating a saponaceous liquid with a current of undissolved air in such proportion as to form soap bubbles, and re eatedly screening the bubbles under the in uence of such a degree of air pressure as can readily be produced by squeezing a hand bulb, until a thick creamy lather suitable for shaving purposes is obtained..

3. A process of forming a thick cream shaving lather from soap bubbles whic comprises the step of repeatedly screening the bubbles under such an amount of gas pressure as can readily be produced by squeezing a hand bulb, until a thick creamy lather suitable for shaving purposes is 0btained.

4. A process of forming. a thick creamy shaving lather from soapy bubbles which comprises the step of repeatedly screening the bubbles with no liquid other than the vesicles of said bubbles, until a thick creamy lather suitable for shaving purposes is obtained.

5. A process of forming shaving lather which comprises maintaining a cake of soap of a kind suitable for use as shaving soap in contact with an aqueous liquid, passing air under pressure only slightly above atmospheric, upwardly through such liquid to form a mass of bubbles and repeatedly screening such bubbles until a smooth creamy shaving lather is produced.

6. A process of forming shaving lather which comprises maintaining a cake of soap of a kind suitable for use as shaving soap, in contact with an aqueous liquid, passing air under pressure only slightly above atmospheric, upwardly through such liquid to form a mass of bubbles and repeatedly screening such bubbles alone, and substantially without other liquid than the walls of the bubbles themselves, until a smooth creamy shaving lather is produced.

7. A process of forming shaving lather which comprises maintaining a cake of soap of a kind suitable for use as shaving soap, in contact with an amount of an aqueous liquid which is not many times more than the amount needed for a single shave, passing air under pressure only slightly above atmospheric, upwardly through such liquid to form a mass of bubblesand repeatedly screening such bubbles until a Smooth creamy shaving lather is produced.

In testimony whereof I have hereunto affixed my signature.
